| 摘 要： | 利用蒙特卡罗工具Geant4模拟了~(137)Cs和~(60)Co这两种放射源的几何形状以及探测距离这两个因素对γ射线在NaI(Tl)闪烁体探测器内能量沉积的影响。研究结果表明,当放射源的几何形状不一样时,不同的核素在峰总比达到最大时的探测距离不一样,模拟结果为放射性测量提供了参考。

| Abstract: | By using Mont Carlo kit Geant4 it has been studied that both the shape of source and detecting distance are able to affect the deposited energy in NaI ( Tl ) scintillation detector. The simulation shows that the measurement distance of radionuclides with reaching maximum peak -to -gross ratio varies with different geometry of sources. |
